These notions of “left and right brain-ness” are widespread and widely accepted. But they may also be wrong
Like the article put, "they may be wrong or right. " the fact is, we shouldn't give ourself more trouble trying to think of which part of our brain we are trying to use because to me they are both the same.
Instead, we should learn to be smart: invest any amount we can afford to have more steem power, learn what the successful ones are doing, learning from our mistakes too...
You analysed it well...keep steeming to more success
